i found a way to get around “cannot GET” errors in webapi (due to CORS - cross origin issue). the answer is [**allOrigins**](https://allorigins.win/) whose catch phrase is " Pull contents from any page via API (as JSON/P or raw) and avoid Same-origin policy problems."

the original problem started because of this behavior:

the link below works in a browser and also works in Postman but does NOT work in Thunkable (due to CORS issues apparently)

`http://numbersapi.com/2000/year?json`

this is the result from a browser:

but when coded in thunkable, it returns with a response “cannot GET”.

Error
```
Cannot GET /web-build/numbersapi.com/2000/year
```

however if you use **allOrigins** , you code the url like this:

`https://api.allorigins.win/get?url=http://numbersapi.com/2000/ye`ar?json

Below is what it looks like when it is entered from a browser. note how the desired url is included in the call. also note that the response of the desired url is now contained as a json variable called **contents**.

this is how to code it in thunkable. (notice the nested json processing)\>

with this result (each successive call gives a different result for the same year)
